Chroma's 63700 Series Regenerative DC Electronic Loads address the testing needs of electric vehicles, fuel cells, energy storage systems, and other emerging energy and high-power applications. Featuring 18kW single-unit capabilities and regenerative design, these loads not only facilitate advanced high-power testing but also return energy back to the grid for substantially increased energy efficiency compared to traditional heat-dissipating methods.
Chroma's 63700 SoftPanel® provides an intuitive software toolset to further enhance user convenience and efficiency as an alternative to manually operating the unit.
▲ The software supports control of up to 10 units of the 63700 series and can connect via GPIB, USB, and Ethernet.
The software currently supports five modes, which can be switched via a drop-down menu:
Set current settings and current slew rate. When Load ON is pressed, the system sinks the programmed load current. The interface also displays the set Von setting.
▲ CC Mode (Constant Current)
Set the desired voltage level, maximum current, and response bandwidth. Upon pressing Load ON, the system sinks current up to the maximum value to maintain the DUT's voltage at the setpoint.
▲ CV Mode (Constant Voltage)
Set the desired resistance value and current slew rate. Upon pressing Load ON, the system calculates and sinks the required current to maintain the set resistance.
▲ CR Mode (Constant Resistance)
Set the desired power level and current slew rate. Upon pressing Load ON, the system calculates and sinks the current required to maintain the set power level based on measured voltage.
▲ CP Mode (Constant Power)
Allows testing with two configurable current levels (L1 and L2) and corresponding time intervals (T1 and T2, adjustable between 0.01 seconds and 100 seconds) for millisecond-level change testing. Additional settings include current slew rate and repetition count for dynamic current variation tests.
▲ CCD Mode (Constant Current Dynamic)
The 63700 SoftPanel® generates reports in both .txt and CSV formats. The sampling interval can be adjusted from 1 to 10000 seconds, and the maximum recording duration is 10000 hours, 59 minutes, and 59 seconds.
